T he apparatus comprises generally a truck A, mounted upon suitabletracks 2, tending along in front of the bank of ovens, and in suitable rlation thereto, seid truck supporting the extracting element and itslaterally edj estable ecrrier B.

C represents an inde iendent supporting truck or carriage upon which ismounted the conveying mechanism and an independent motor 3 by which bothtrucks, coupled together es shown, are moved along the track from oneoven to the other intermittently and by which motor the conveyingmechanism is actuated.

The conveying mechanism, forming e portion of the invention which is thesubiect filed herewith, is not speeiiieslly t eseribed herein, andshell` be only generally referred to in4 order to give a fullunderstanding of the operation and functions of the drawing apparatus,which is the particular subject metter herein set forth. i

ln designing the truck, the rem carriage, and the other parts of themechenism, vve have utilized es fer ets-possible structurel steel,thereby securing greet strength, lightness, rigidity and economy. Thetruck A comprises e mein framework composed of structurel side and 'endsills 4 and 5 of chennel` or other suitable form, withintervei'iingtransverse sills (3 and .e cover plete .7 or its' equivalent, Whichforms the mein supporting structure-l platform of' the truck mounted bysuitable bearings on axles 8, 8, having supporting Wheels 9, l0, runningon tracks 2Q As shown the inner Wheels 9 are quite broad und liet merelyresting on the top oi the inner rail, While the outer Wheels it() ereheavily flanged so es to embrace the heed of the ruil and. bruce thecarrie-ge against the strains in either direction due to the extractding operation in inserting or withdrawing .the shovel. l v

A further advantage of such arrangement oi Wheels ,is that anyvariations es to erellelism of the reils will not materially a ect theoperation of the apparatus being compenscted for by' the vextre'vvidefeces ofthe inner wheels 9. The truck A seing coupled to the conveyercarriage C es shown, is either til pushed or pulled by said carriage andis not therefore necessarily provided with any self-contained propellingmotor or mechanism, although it will be understood that if desired thetruck A and its extracting apparatus may be employed entirelyindependent of the conveying mechanism and provided with propellingmeans.

The ram carriage B comprises a structure of any suitable or convenientforni, so arranged that it maybe moved laterally to the right or theleft, preferably in an arc-A shaped track, entirely inde endent of anypivotal or other guiding or limiting connection with the main truck A,but will, however, generally-conform, to its swinging position, to atheoretical. center. Such center is indicated in Fig. 2 at a; and isprefer abl r adopted at or about a point in front of the mechanism whichwill correspond to sueh a position with relation to the oven that theangle of the ram may beso arrangedl as to ch all parts of its interior.The position f theram is thereby controlled solely by the arc-shapedtrack-way by which the ram carriage is guided or its equivalent, andthis is a distinctiveand valuable feature of our in' vention. l

The arc-shaped track-Way referred tol forms an integral portion of truckA, and as shown, is built up from the up er surface thereof by meansl offront and acl( angle bars 11, 12, having a radius'converging to thecenter ze, either exactly or approximately, secured upon the plate 7 ofthe ram carriage by rivets or bolts, and preferablyH extendingfrom oneend to the other thereof. The ends of said annular track-way arepreferably inclosed by walls 13, 13, to limit .the .lateral travel ofthe ram carriage.

As'sllown in the drawings, the ram car ringe B is constructed of upper'and lower plates 14, a15, mounted upon casters or rollers 17, 17, ateuch side of its'center ur- ,ranged to run upon the surface of plate 7,While beyond said casters 17 at each side are verticall arranged guidingrollers 18, 18,

mounter on studs below the rain carriage frame and projecting betweenthe curved angles or guides 11, l2. At its forward end` theram carriageis supported upon an additional caster or roller 1Q mounted by itsYshaft 20 in a shoe 2l with interposing cushion springs 22, 22, by whicha certain amount of resiliency is provided to coinpensate forinequalities in the level of the oven' floor or vertical deviation ofthe ram. As thus constructed it will be seen thatas the ram carriage ismoved to the right or the left it will at all times conform t'o thecurved trackway; will-be substantially supported on the flat u per faceof the main truck plate 7, and l may lleadjustcd entir'ely independentthereof bly the following means.

23 is a sprocket chain, cable, or other suitahle flexible transmittingelement connected at its en ds. 24, 24, to the under side ofthe ramcarriage in any suitable manner as by 'the construction shown in Fig. 8,and passing around sprocket wheels or sheaves 25, 26, so located as togive the desired range of movement when one of said sprockets isactuated. Positively-actuzitcd sprocket 2G is mounted upon the upperendof shaft 27 extending downwardly through plate 7 or a suitablehearing thereon and isv provided with a bevel wheel 28 into which meshesthe driving bevel 29 of the transmission gearing of a motor 3Q, allofsaid gearin and motor being conveniently mounted be ow the plate 7 ofthe truck,v and du ported thereby, as clearly shown. We pre er to employfriction gearing or other suitable slip age mechanism between the motor30 andpshalt 27', for which purpose the motor pinion and its driven-gear may be smooth faced'. The advantage of such arrangement is thatbreakage'of thegearing is' avoided should the'rain carriage be thrown,too 'far to either side., or encounter any re-` sisting obstruction'. Bythis construction the chain 23 may be actuated ineither directionand theram carriage located at the desired position by the. motor 30 as will beunderstood without further description and. un-

4der the complete control of the operator.

31 is the rain which is preferably in the.

form of a tube, having secured to itat one side a i'aclc 32 into whichmeshes pinion 33 on shaft 34', mounted in suitable bearings 35,35,

below and above the main' truck construction as clearly shown inFig'.3., Shaft 34 is provided with a driven bevel wheel of dish torniwhereby'r to provide clearance for the friction clutc 37 of thed-rivingtmotor 38.

upper side oi the ram carriage B'tra`veling with it, andactuates shaft34 by means of bevel pinion 39 engaging driven bevel 36 as will bereadily understood, whereby to transmit inward or outward movement tothe r'am 31 as desired. IThe friction clutch 37, shown in detail in Fig.10, is so constructed thatit will ordinarily transmit the energy of thevmotor to the pinion 33' to' aetuate the ram, until an excessive strainis encountered, as for instance by the shovel of the ram coming intocontact with the back wall of the oven on forward travel, or by makingcontact with the door jambe or other obstructions on back 'Said motor is.mountedas shown upon th'e .105

Atravel, also preventing wear or breakage of 120 the gear teeth on'reversal of the motor, wliereu on sli page willoccur/and no dan1- agewil be one? Also, if "the extractor makes cpntact during its operationwith any obstruction suHicient to overcome the trans initting effect ofthe friction driven mechanism, sli page will occur, allowing theobstruction to e passed'asiby slewing. around of the ram to pass,the do)r jamb.

'ln the construwiion shown in Fig. l() the Cil dotted lines. Upon'withdrawal of the ram, the shovel will resume its normal osition. t. InFig. 12 we have shown a detai view of means for preventing upwardtipping of the rain carriage, consisting of one or more rollcrs 63depending by bracket 64 below plate 15 of the ram carriage and engagingunderneath an angular' bearing track 65 secured to the upper l'aceofplate 7 of theram carriage A. Ordinarily such mechanism will not benecessary except asa safeguard against tippin ffas the ram carriage isdesigned to maintain its center of gravitv at all times.

The operation of t e invention will be readilyl understood from t eforegoing description.. 13g-"Motion being transmitted to the main truckA by4 means of the conveyer carand its motoras' described, or in anyother suitable way 'as by traction mechanism mounted lon the main truckA itself', and the truck having been ositioned in front ofthe oven to bedrawn? e extractinfr rain is preferably located in the central positionas shown.`

in Fig. 2 for initial operation. Thecoke adjacent to the door haylingbeeniremoved, the ram carriage may then be adjusted-laterally either tothe right or the left, whereupon the extractor maybe inserted to eitherside and. the contents'removed therefromthe operation being continued bylocating the extractor at va ying .angles until the bven is einptied.construction of the itam beam 31 isfsuch that it willwithstand thevarious strainsftowhich it is subjected and may be considerablydeflected as by c'oming int contact with the'jambs of the door withoutinjiir while the arrangement -of the parts is suc that the center o fgiavity of the ram carriage and its elements is always within itsbearing points in any position ot'. the extractor', thereby preventingtipping, as stated.

lt will be understood that' any available 'power mechanism maybe em)loyed and that. We do notdesire to be limite to electric inotors,`although siichare convenient for the etLuipment and operation ofthe-apparatus w ere current is available.

The loivcompact construction of themachine enables it to be used on-yards having a nOrmallevel of track Without necessitating any changeAin the grade, so that it in no way interferes with the ordinary handdrawing operation as would be the caseif grading were. required. rlheoperator' may at all times see into .tho oven without stopping..

thus enabling hin'ito run the machine qwith case and facility. y

The invcntionmay be variously changed or modified in construction,design or in diff feront details by the skilled mechanic, but all suchchanges are to be considered as within.
